We go to DW very often. We were there last October, and then in February, July, and just now. We loved our July trip, when the parks were very empty and the ride lines were very short. I was NOT impressed with the crowds and lines this time. What a contrast.
First of all, I have to agree, STAY AWAY FROM EPCOT ON WEEKENDS. The lines for the food kiosks are just to long. The crowds are just too high. The ride lines are too long. In some cases, we needed to wait almost 2 hours for some rides.
Hollywood Studios is quite busy, and if you really want Boarding Passes for Rise of the Resistance, you really do need to plan to be out at the bus stop by 1 1/2 hours early, or, honestly, you won't be in the park on time. The lines for the buses to Hollywood Studios in the mornings are insane, and then you get there and have to wait through insanely long lines for security, and gate entry. There was one morning where we went out to take the bus, and were at the bus stop one hour and 15 minutes early, and could see we weren't going to make it. So we took an UBER and, with security lines and everything we just barely made it into the parks on time. A second group in our party was 10 minutes behind us. They still arrived at the bus stop over 1 hour before opening. They also called an Uber, which came fast, but not fast enough. They just missed getting into the park in time for Rise of the Resistance.
Crowds are big enough, and enough restaurants are closed, that Dining reservations were unavailable at almost all of the decent restaurants almost all of the time, unless you snag them well in advance before you go on your trip. Even Bier Garten which normally almost always has room, was 100% full, right until closing on most days, and 'Hollywood and Vine' and '50s Prime Time Cafe' never even showed up on the app as having times, ever.
With the parks being full enough that crowds are now something of a problem, at times, with and with RIDE WAIT TIMES NOW BEING EVERY BIT AS LONG AS 'NORMAL' IN THE PAST, I can no longer recommend that people go because 'Covid has made the parks nice, and empty and easy.' Honestly, there are now no advantages to going, compared to going at normal times. However, if this is the time you can go, then go. It is still good. We have another trip planned for late January to stay at Boardwalk. I suspect the crowds and wait times will still be higher when we get there.
